During the
1962 election, Martin served as attorney general candidate
Edward Brooke's campaign coordinator in the
suburbs west of Boston. When Brooke took office in January 1963 he named Martin Chief of the Financial Division. While in this position, Martin felt that he needed a better background in tax law, so he attended
Boston University School of Law at nights and earned a master of laws in taxation. When the position of First Deputy Attorney General opened up in 1964, Brooke appointed Martin. As First Deputy, he was responsible for the day to day operations of the Attorney General's office. He also maintained a private law practice during this time. ==Attorney General==
